Abstract
A sound attenuated conveyor roller assembly reduces the noise or vibration produced by the conveyor roller assembly during operation, and includes a conveyor roller having a cylindrical portion to which a sound damper may be coupled. The conveyor roller may include an unreduced outer surface and a reduced outer surface, in which the sound damper is disposed at the reduced outer surface such that an outer surface of the damper and the unreduced outer surface of the conveyor roller are located at substantially equal radial distances from a longitudinal axis of the conveyor roller. A tapered end connector having a tapered plastic tip may be coupled to each end of the conveyor roller to further reduce noise and vibration in the conveyor roller assembly.

A sound attenuated conveyor roller for a conveyor assembly, said sound attenuated conveyor roller comprising
- a roller body having an exterior surface, a pair of opposed ends, and an interior;
- a pair of internal bearings disposed within said interior of said roller body;
- a pair of connectors, with one connector of said pair of connectors at each of said opposed ends and each said connector engaged with a respective internal bearing of said pair of internal bearings and with a portion of each said connector extending from a respective end of said roller body, wherein said roller body is able to rotate relative to and about said connectors;
- and
- a sound dampening sleeve disposed over said exterior surface of said roller body, wherein said sound dampening sleeve is nonmetallic and defines an outer surface of the sound attenuated conveyor roller;
- wherein said connectors are configured for mounting said sound attenuated conveyor roller between frame side walls of said conveyor assembly.
A conveyor assembly, said conveyor assembly comprising:
- a pair of frame side walls that are spaced apart from one another and a plurality of sound attenuated conveyor rollers mounted to and between said frame side walls, wherein said sound attenuated conveyor rollers define a conveying surface for conveying objects, and wherein each said sound attenuated conveyor roller comprises;
- a roller body having an exterior surface and a pair of opposed ends;
- a pair of connectors, with one connector of said pair of connectors at each of said opposed ends and with a portion of each of said pair of connectors extending from a respective opposed end of said roller body with said roller body configured to rotate relative to and about said pair of connectors;
- and
- a sound dampening sleeve disposed over said exterior surface of said roller body, wherein said sound dampening sleeve is nonmetallic and defines an outer surface of the sound attenuated conveyor roller;
- wherein said pair of connectors of each said sound attenuated conveyor roller are mounted to respective ones of said frame side walls such that said sound attenuated conveyor rollers extend between said frame side walls.
A sound attenuated conveyor roller, said sound attenuated conveyor roller comprising
- a roller body having an exterior surface, a pair of opposed ends, and an interior;
- a pair of bearings with one of said pair of bearings disposed at each of said pair of opposed ends of said roller body;
- a pair of connectors, with one of said pair of connectors at each of said pair of opposed ends and each of said pair of connectors engaged with a respective one of said pair of bearings and with each of said pair of connectors having a portion extending from a respective opposed end of said roller body, wherein said roller body is able to rotate relative to and about said pair of connectors;
- and
- a sound dampening sleeve disposed over said exterior surface of said roller body;
- wherein said exterior surface defines a first outer diameter and a second outer diameter, and wherein said first outer diameter is smaller than said second outer diameter and said sound dampening sleeve is disposed over said exterior surface only at said first outer diameter, and wherein said sound dampening sleeve extends over a majority of a longitudinal length of said roller body.
The sound attenuated conveyor roller of claim, 25 wherein said sound attenuated conveyor roller comprises a driven roller.
